The presented investigations define the influence of the lapse of time between magnetic biostimu-lation and sowing on crop yield, and the influence of seed orientation in the magnetic field during pr...
The effect of pre-sowing magnetic biostimulation of wheat grains on germination and yield is presented. Two magnetic exposure doses were used. The results show that a magnetic field influenced the ger...
Investigation carried out at the Department of Physics, University of Agriculture in Lublin consisted in the application of an alternating magnetic field (50 Hz, harmonic vibration) for the biostimul...
The influence of a variable magnetic field of 30 mT magnetic induction and frequency f = 50 Hz, at different exposure times (8, 15, 30, 60 and 120 s), as well as an electric field of 5 kV cm-1 intensi...
